T 0 all whom it may concern:

Be it known that I, GEORGE W. BEADLE, a citizen of theUnited States ofAmerica, and a resident of New Rochelle, New York, have invented a newand useful Improvement in Collapsible Vibration-Absorbing Supports,which invention is fully set forth in the following specification.

This invention is intended primarily for supporting phonog'raphs when inuse upon railway trainsor automobiles, but may be used fortypewriting-machines and in other service where the instrument-is to bepro tected from the jolts or jars due either to travel or to thevibrations'of near-by machinery, etc.

The invention comprises broadly a framework carrying and positioning aplurality of shock-absorbing devices. More specifically the inventioncomprises two cross-arms centrally pivoted together, and carrying attheir ends suitably-cushioned seatsfor the corners of the phonograph orother device to be supported, and provided also with suitablecushioning-devices to rest upon a table or other support withouti'njuryto the latter. The invention also comprises the feature ofconstructlon and arrangement hereinafter set forth and claimed.

The invention may be embodied in' different concrete forms but for thesake of clearness the following specification and the accompanyingdrawings set forth one pre-' ferred embodiment for use with the com--mercial dictation-machine known as the dictaphone. In said drawings?Figure 1 represents a front elevation o the device, the phonograph beingconventionally indicated in outline only;

Fig.2 is a plan of the same dev1ce,the

' phonograph being removed; and

cpeni in the same horizontal plane. there willbe a definitepredetermined limit Fig. 3 represents, on a larger scale, a detail isseated with its four corners resting 1n the work consists of the twocross-arms 1 and 2,

shown as two flat horizontal bars, pivoted together at their center, asb a rivet 3; and near each end of one memi ier (as 2) is an offset 4, sothat all four'outer ends will lie Preferably for the movement of' thetwo arms when n as byacurved slot-5 in one member :7 and a d ependlngp1n6 in the other -at being" understood that when opened into theirpredetermined extreme positions (as indicated in Fig. 2), the four endsof the arms will be properly positioned for receiving the four cornersof the particular phonograph (or other instrument for which theparticular framework is designed).

Above the end of each arm is secured a boss 7, preferably circular; andbeneath the same is secured a cushion 8, preferably of rubber, suitablyheld in place as by a headed screw 9 passing through a washer 10 andthreaded into the end of the cross-arm (and into its boss also, ifdesired).

One or more convolutions of the lower end of a comparatively-stiffupright helicalsprin 11 are engaged snugly around the boss where theyare secured in place in any suitable manner, as by solder. The

upper. end of each springll carries a seat 12 for one corner of thedictaphone. This seat is shown as a substantially-rectangular platehaving aroundtwo sides an upturnedflange, to provide a three-sidedconcave corner to fit the convex corner of the dictaphone; and thecentral portion of said seat is cut awa to leave an aperture 13 with aplurality o integral fingers 14, here shown as three in number, whichare then bent down to engage within the helix of the spring 11, wherethey are suitably secured to the spring, as by being bent slightlyaround the wire constituting the convolutions thereof, or by solder orthe like.

In. traveling, and for shipment, the two arms are folded up as nearparallel as possible, so as to occupy less-space than when opened out.In order to use the device, the arms are opened out as far as the slotand pin (5 and 6) will permit, as indicated in ig. 2, and then placed ona table or other suitable support; and then the phonograph ducingsounds. a

One form of the invention has thus bee described with full detail, butonly for the sake of clearness, since the invention is not limited tothe precise construction and arrangement here set forth, but might beembodied in various forms, and parts might be transposed or inverted orotherwise modified within the spirit of the invention. For instance,although the drawings show the framework made up of two arms centrallypivoted together, yet it is obvious that they might be pivoted otherwisethan centrally, and that there might be a greater number of arms thantwo; also that the shock-absorbers might be provided at only two of theadjacent corners of a rectangular device, reliance being had upon thelateral rocking thus provided for absorbing some part of the shock. Butthe symmetrical form set forth, with the two centrally-pivotedcross-arms and the four shock-absorbers, is believed the most desirablearrangement.

The invention having been thus described. what is claimed is-- 1. In acollapsible support, the combination with two pivoted cross arms, ofvibration-absorbing means at each terminal thereof, each said meanscomprising a cushion and boss secured on opposite sides of the terminal,an upright helical spring secured to said boss, and a centrallyapertured cor-c ner-supporting seat resting upon said spring and havingdownturned fingers secured to the same.

In a shock-absorbing support, the combination of a pair of memberspivoted together between their terminals, means carried by each terminalcomprising on one side thereof a cushion pad and on the other side aspring and an article receiving cap mounted on the spring, and a singlemeans for maintaining the pad and spring in axial alinement.

In a shock-absorbing support, the combination of a pair of memberspivotcdtogether between their terminals, each terminal being providedwith a block on its upper side, a solid cushion on the other side of theterminal beneath said block, means passing through the cushion and theterminal into the block for securing the three members in fixedrelation, a coil spring centered over said block. and anarticle-receiving cap supported by said spring.

in testimony whereof I have signed this specification in the presence ofa subscribing witness:

GEORGE W. BEADLE.
